We've got Looper's Rian Johnson live and on io9 taking your questions. Ask him absolutely anything you want about time travel, paradoxes or the difficulties of transforming Bruce Willis' sour face into Joseph Gordon-Levitt. Rian will be online for one hour, and one hour only — so make with the questioning (spoilers ahead).

We only ask that you refrain from asking questions that have already been submitted.

At 1:00 PDT, he will will sign on and tackle as many questions as he can. You know the rules - he's volunteered to drop by the io9 house, so be polite!

UPDATE: The conversation has been closed. Thank you for your questions, and thank you Rian for your answers!
